A test is conducted in 22 cities to see if giving away free transit system maps will increase the number of bus riders. In a regression analysis, the dependent variableÂ YÂ is the increase in bus riders (in thousands of persons) from the start of the test until its conclusion. The independent variables areÂ X1Â = the number (in thousands) of free maps distributed and a binary variableÂ X2Â = 1 if the city has free downtown parking, 0 otherwise. The estimated regression equation is
In city 3, the observedÂ YÂ value is 7.3 andÂ X1Â = 140 andÂ X2Â = 0. The residual for city 3 (in thousands) is:
